【正文】 started turning and continue to increase the pressure until the joint control of the situation, the export axle assume full power output. CST fluid mechanics device known as Nien large Daishishusongji soft start system in the country39。 But lubricant sealed perspective, the viscosity can not be too low. Provide lubrication and therefore should meet the requirements of sealed premise as a lowviscosity liquid to improve hydraulic ponents transmission efficiency. Wen Xing Nien also called liquid than for the hightemperature or lowtemperature, and still maintain an effective lubricant sealed. Secondly. A greater emphasis on the hydraulic ponents for the moment and the power transmission and liquid working for the redirect, it is liquiddegrees the higher the better. Thirdly. The performance can have a stable bubble, aging and sedimentation. Fourthly. Suanzhi sealed pieces to be neutral to low, and a good patibility, not dwell inflation, not dissolved the noncorrosive metal. Fifthly. A higher flash point and lower congeal point hydraulic ponents work Youwen change significantly, sometimes up to 160 degrees, and therefore require flash point higher than 180 degrees, and congeal point lower than 20 degrees, lowtemperature environment for the benefit of the startup of hydraulic ponents. Sixthly. A good lubricant performance liquid sufficient greasiness to the good parts in the surface material, a good lubricant. At present, and hydraulic transmission applications work more liquid types, among all oilbased products, has used the water or other liquid Nanran (coal mine explosion and fire in defense applications). Domestic hydraulic ponents monly used 6th hydraulic transmission oil (also useful 8th hydraulic transmission oil), and sometimes to 22 turbine fuel substitution. Diesel oil is dedicated to the life of not less than 2,000 hours and for the initial operation of new equipment installed oil after 100 hours and 500 hours of the first, second formula, can still be used after the filter. Is one of the following situations, the need to replace the new oil : Water content greater than %。為了滿足規(guī)定的性能要求，可用不同 的有機(jī)取代基或調(diào)整聚合物分子的大小 (即改變其分子量 )，以變化其粘度或獲得其它性能。汽車用的硅油風(fēng)扇離合器主動(dòng)盤(pán)與發(fā)動(dòng)機(jī)相聯(lián)，從動(dòng)盤(pán)與風(fēng)扇相聯(lián)，工作液體為粘度較大的硅油。保定螺旋漿制造廠設(shè)計(jì)、生產(chǎn)了與之結(jié)構(gòu)相似的產(chǎn)品。 目前國(guó)產(chǎn)液粘調(diào)速離合器多采用 8 號(hào)液力傳動(dòng)油為工作液體。當(dāng)控制壓力足夠時(shí)小，主、從動(dòng)摩擦片脫離，則輸出轉(zhuǎn)速為零。以上各條對(duì)內(nèi)燃機(jī)車專用油以外的液力傳動(dòng)油也有一定的參照價(jià)值。 性能穩(wěn)定 不易產(chǎn)生泡沫、老化和沉淀。由于液粘傳動(dòng)產(chǎn)品 (如液粘調(diào)速離合器 )與液力傳動(dòng)產(chǎn)品 (如調(diào)速型液力偶合器 )雖有本質(zhì)上的不 同，但由于有相似的性能和相同的用途 (調(diào)速節(jié)能 )，在若干技術(shù)活動(dòng) (如制訂發(fā)展規(guī)劃、 標(biāo)準(zhǔn)、技術(shù)管理、訂貨活動(dòng)等 )中均被視為同一類型，與液力行業(yè)有共性，故本文另辟章節(jié)介紹其產(chǎn)品結(jié)構(gòu)和傳動(dòng)用油。 國(guó)際上液力偶合器產(chǎn)品以德國(guó)福依特公司最為著名，據(jù)資料稱已有轉(zhuǎn)速達(dá)20200r/min、 功率達(dá) 55000kW 的產(chǎn)品，可見(jiàn)我國(guó)與之尚有相當(dāng)大的差距。液力偶合器的基本構(gòu)件是具有若干徑向平面葉片的、構(gòu)成工作腔的泵輪和渦輪。 附件 1：外文資料翻譯譯文 流體傳動(dòng) 流體傳動(dòng)包括氣體 (壓 )傳動(dòng)和液體傳動(dòng)，液體傳動(dòng)分為液壓傳動(dòng)、液力傳動(dòng)和液粘傳動(dòng)。廣泛應(yīng)用于帶式輸送機(jī)、刮板輸送機(jī)、球磨機(jī)、風(fēng)機(jī)、壓縮機(jī)、水泵和油泵等設(shè)備的傳動(dòng)中，提高傳動(dòng)品質(zhì)并節(jié)約能源。石油機(jī)械應(yīng)用較少，功率達(dá) 1500HP。因此應(yīng)在滿足潤(rùn)滑和密封要求前提下，盡量采用粘度低的液體，以提高液力元件傳動(dòng)效率。國(guó)內(nèi)液力元件通常采用 6 號(hào)液力傳動(dòng)油 (也有用 8 號(hào)液力傳動(dòng)油的 )，有時(shí)以 22 號(hào)汽輪機(jī)油替代。主動(dòng)摩擦片及輸入軸與動(dòng)力機(jī)相聯(lián)，輸入轉(zhuǎn)速可視為常量。 (3)有良好的氧化安定性。 液粘調(diào)速裝置 當(dāng)前生產(chǎn)和應(yīng)用的有兩類不同結(jié)構(gòu)的液粘調(diào)速裝置，一類是美國(guó)費(fèi)城齒輪公司生產(chǎn)的平行軸液粘調(diào)速裝置，輸入轉(zhuǎn)速 1785r/min，輸出轉(zhuǎn)速 5000r/min，傳遞功率達(dá) 5200kW。 硅油風(fēng)扇離合器與工作液體 硅油風(fēng)扇離合器的主、從動(dòng)盤(pán)上各有若干緯向環(huán)狀葉片，兩者的環(huán)狀葉片相互交替的插入，構(gòu)成若干園環(huán)狀間隙 (油膜 )，利用這些間隙中油膜的粘性來(lái)傳遞動(dòng)力。燃油效率高，噪聲小，延長(zhǎng)發(fā)動(dòng)機(jī)使用壽命。 附件 2：外文原文 Transmission of fluid Former statement fluid transmission is including gas (pressure) transmission and liquid transmission, hydraulic transmission into liquid transmission, hydraulic transmission and fluid Nien transmission.
